Application filed July 5,

in a carpentcrs vise, and my object is to provide a simple and inexpensive form of vise which is adapted to be rotatably supported and to effect self-locking against rotation when the work is clamped tightly in the vise. j i '7 l in the accompanying drawing, Figure 1 is aplan view ofinyimprovedvise partly open, and Fig. 2 is a corresponding view to Fig. 1, but showing the vise in section.

F 3 is a vertical section of a vise on line 3-8, of lhg. 1, and Fig.4: 1s a cross section and end view of ttVlSQ on line l --45 of Fig.

1. Fig. 5 is a sectional view of the main jaw body of the vise, and Fig. 6 is an elevation and section of the movable jaw and screw.

The vise comprises a main body portion 2liaving a round offset or boss 3 with a round opening 4: extending therethrough.

A jaw 5 projects laterally at one side of boss 3 and separate short and long arms 6 and 7 respectively extend from boss 3 in theopposite direction to jaw 5, the boss being divided or split between said arms. Longer arm 7 has a rectangular opening 8 extending therethrough, and an olfset or foot 9 forms an integral part of the outer end of arm 7 so as to provide an extended bearing face 10 for the square or rectangular shank 11 of movable jaw 12, shank 11 being at right angles to jaws 5 and 12 and adapted to slide freely through opening 8 and arm 7. The flat side faces of shank 11 are also adapted to slidably engage the flat end face of short arm 6 between the short confining flanges 14 -14L at the top and bottom sides of said arm 6. Shank 11. is thus supported and caused to travel in a straight line across and through the ends of arms 6 or 7 andto act in conjunction with foot 9 in sustaining the clamping pressure imposed upon the jaws when a piece of work is held therebetween and the jaws are tightened by screw 15. This screw extends through the base portion of jaw 12 and is free to turn therein and held in place Specification. of Letters Patent.

screw extends the full length of shank 11 and is parallel therewith and also slidably spaced apart from said shank sothat it may pass through both arms 6 and 7 at a point relatively near the edge of the round opening and between said opening 8 in arm 7. The bore 19 through arm 7 permits screw 15 to turn and slide freely therein and the opening for the screw in arm 6 is screwthreaded so that screw 15 may be engaged to move jaw 12 back and forth in respect to jaw when the screw is rotated by handle 17. Moreover, when the work is pinched between the jaws, screw 15 will also draw arms 6 and 7 together or toward each other and thereby act to clamp the boss or hub portion 3 upon the round supporting stud 20 within opening 1. A base flange 21 for stud 20 provides a seat and rest for the vise body 2 through its hub 3, and a screwthreaded stem 22 extends downwardly from base 21 and through an opening in the table or bench 23 where it may be engaged by a thumb nut 24; and washer 26 to lock the stud in fixed position upon said bench or table. Ribs 27 upon the bottom side of base 21 prevent stud 20 from turning.

The relation of the screw to shank 11 and the vmovable jaw and engagement of the split body by the screw at a point between shank 11 and stud 20 permits an exceptionally eflective clamping action to be obtained at the jaws and on the stud, and this arrangement of parts simplifies and reduces the cost of the manufacture of the two jaw members of the vise and makes them easy to assemble, and all the parts including the screw are accessible and easily reached for oiling and inspection. The vise body is also easily removed from the stud and inverted to place the jaw in a different position upon the bench, and the stud may be secured to extend vertically or horizontally from any suitable support and is especially useful for carpenters and other wood workers, being convenient to attach and remove from a bench or other support and small and compact enough to place and store in a toolbox.

What I claim is:

i 1. A vise, comprising a main body portion having a jaw and a hub with an opening extendin therethrough, short, and long arms at one side of said hub, the longer arm having rectangular openings and there being a bore therethrough and said short arm having a screw-threaded opening in register with said bore, and a movable jaw having a rectangular shank extending through the opening of said long arm and provided with a screw extending through said bore and opening in said pair of arms.

2. Avise,c0mprising a main body having a jaw and a split hub and pr vided with parallel arms of different length, one of .said arms having a screw-threaded opening and the other arm having a. bore adapted to receive a screwfor said threaded openingand provided with a larger rectangular openlng at one side of said bore adapted toreceive the shank of a movable jaw, and a-movable jaw having a shank at one side thereof, and a screw swiveled within said movable jaw parallel with said shank.

3. A vise, comprising a body portion having .a split hub, a pair of arms provided with registering openings adapted to receive a screw and one of said arms having a rectangular opening, the other arm having a-flanged end portion opposite said 'angularopening, a movable jaw having an annular .shank extending through said angular opening in one of aid arms and slidably seated within the flanged extremity of the other arm, a screw swiveled within said movable jaw and extending parallel with and at one side of said shank through both of said arms intermediate said hub and said shank, and a supporting stud for said body upon which said hub is adapted to he rotatably mounted.

4. A vise, comprising a main body hav ing a jaw and an offset hub and a short and a long arm, said longer arm having a toot extending laterally from its outer end and provided with an angular rmenin; in line with said foot and being further provided with a bore at one side of and parallel with said opening, and said shorter arm having a screw-threaded opening axially in line with said bore, and a flanged extremity in line with angular opening in said longer arm and the hub being split between said arms, a movable jaw having a right-angled extension adapted to pass through the longer arm and engage the flanged extremity ol said shorter arm, a screw swiveled within said movable jaw and extending through said arms in screw-engagement in the screwthreaded shorter arm, and a'stud adapted to snugly fit within said hub having means adapted to secure the same in a fixed position upon a support.
